Here's the full procedure:
1. Begin the test with the ignition switch in the Off position.
2. Depress the trip odometer reset button.
3. While holding the trip odometer reset button depressed, turn the
ignition switch to the On position, but do not start the engine.
4. Keep the trip odometer reset button depressed for about ten seconds,
until CHEC appears in the odometer display, then release the odometer
reset button.
5. A series of three-digit numeric failure messages may appear in the
odometer display, depending upon the failure mode. If a failure message
appears, see the Instrument Panel, Gauges and Warning
Indicators/Instrument Panel/Instrument Cluster Failure Message chart for
the description and proper correction. If no failure message appears,
the Self-Diagnostics will proceed as described in Step 6.
6. The cluster will begin the odometer walking segment test. This test
will require the operator to visually inspect each odometer segment as
it is displayed to determine a pass or fail condition. First, all of the
segments will be illuminated at once; then, each individual segment of
the odometer display will be illuminated in sequence. If any segment in
the display fails to illuminate, repeat the test to confirm the failure.
If the failure is confirmed, replace the faulty instrument cluster.
Following the odometer walking segment test, the cluster Self-Diagnostic
Test will automatically proceed as described in Step 7.
7. The cluster will perform a bulb check of each indicator lamp that the
cluster circuitry controls. If an individual amber indicator lamp does
not illuminate during this test, the instrument cluster should be
removed. However, check that the incandescent lamp bulb is not faulty
and that the bulb holder is properly installed on the circuit board
before considering instrument cluster replacement.
8. If the bulb and bulb holder check OK, replace the faulty cluster.
Each of the red indicators are illuminated by a Light Emitting Diode
(LED) . If an LED fails to illuminate during this test, the instrument
cluster must be replaced. Following the bulb check test, the cluster
Self-Diagnostic Test will automatically proceed as described in Step 8.
9. The cluster will perform a gauge actuator test. In this test the
cluster positions each of the gauge needles at three different
calibration points, then returns the gauge needles to their relaxed
positions. If an individual gauge does not respond properly or at all
during the gauge actuator test, the instrument cluster should be
removed. However, check that the gauge terminal pins are properly
inserted through the spring-clip terminal pin receptacles on the circuit
board before considering instrument cluster replacement. If the gauge
terminal connections are OK replace the faulty instrument cluster.
10. The Self-Diagnostic Test is now completed. The cluster will
automatically exit the self-diagnostic mode and return to normal
operation at the completion of the test, if the ignition switch is
turned to the Off position during the test, or if a vehicle speed
message indicating the vehicle is moving is received from the PCM on the
CCD data bus during the test.
Go back to Step 1 to repeat the test, if required.

Check your FSM; that was sent to me for the FAQ and I know for sure it
works for '99 and '00.
If you remove the needles for a face replacement, just put one on at any
spot for the first run. They stop 3 times; then the needle you put on
stops, put another needle on at the appropriate location. Then remove
the one you put on first and re-install where it should be.
Took me 3-4 cycles before I got them all set right. Can't fix all 6
with only 3 stops in the cycle.
